Announcing NetBSD 2.1 Introduction The NetBSD Project is pleased to announce that release 2.1 of the NetBSD operating system is now available. About NetBSD 2.1 NetBSD 2.1 is the first maintenance release of the netbsd-2 release branch. This release provides numerous functional enhancements, including support for many new devices, hundreds of bug fixes, patches and updates to kernel subsystems, and many enhancements to the user environment. In addition, all of the security fixes and critical bug fixes from the NetBSD 2.0.3 update are included as well. Complete source and binaries for NetBSD 2.1 are available for download at many sites around the world. A list of download sites providing FTP, AnonCVS, SUP, and other services is provided at the end of this announcement; the latest list of available download sites may also be found at:

We encourage users who wish to install via a CD-ROM ISO image to download via BitTorrent by using the torrent files supplied in the ISO image area. BitTorrent has recently been added to the list of distribution mechanisms and its use is strongly encouraged to help keep bandwidth available. About NetBSD The NetBSD operating system is a full-featured, open source, UNIX-like operating system descended from the Berkeley Networking Release 2 (Net/2), 4.4BSD-Lite, and 4.4BSD-Lite2. NetBSD runs on 54 different system architectures featuring 17 machine architectures across 17 distinct CPU families, and is being ported to more. The NetBSD 2.1 release contains complete binary releases for 48 different machine types. NetBSD is a highly integrated system. In addition to its highly portable, high performance kernel, NetBSD features a complete set of user utilities, compilers for several languages, the X Window System, firewall software and numerous other tools, all accompanied by full source code. The NetBSD Packages Collection contains over 5500 packages and binary package releases for a number of platforms are currently in progress. More information on the goals of the NetBSD Project can be procured from the NetBSD web site at:

NetBSD is the work of a diverse group of people spread around the world. The Net in our name is a tribute to the Internet, which enables us to communicate and share code, and without which the project would not exist. Major Changes Between 2.0 and 2.1 The complete list of changes can be found in the CHANGES-2.1 file in the top level directory of the NetBSD 2.1 release tree.
